Minnie, who has supported the charity over the past two decades, said in a statement: “I am nothing short of horrified by the allegations against Oxfam International.

“In no uncertain terms do I plan to continue my support of this organization or its leaders.

"And though it is unfortunate that after 20 years I am no longer able to advocate and defend through this specific framework, social and economic injustice is more globally prevalent than ever.

"I certainly will not let the abhorrent mistakes of a troubling organization stop me or anyone else from working with good people in this space to support a population of human beings around the world that needs our help.”
